Soluser Solar Charger 25000mAh, Portable Solar Power Bank External Backup Battery, 2 Outputs-5V/2.1A & 1 Micro USB Input-5V/2A Huge Capacity Phone Charger for Smartphones, LED Flashlights for Outdoor

Generally, this unit is pretty good. 25,000 MaH capacity, rugged design and construction, half decent l.e.d. torch/flashlight built in. My only complaints are that the button that turns the torch on and the unit is not protected from rain and also the unit now seems to be malfunctioning when you top it up via the solar panel - the 4 lights that show when it is charging and the level it's reached are flashing randomly when placed in a light source, rather than being on to show full charge or the progress of the charge. Were it not for these issues, product would have recieved 5 stars. I shall still keep it, however, as it is still a fairly functional.***EDIT 10TH FEBRUARY 2020***The tab that holds the cover on just broke off really easily, now exposing the input and outputs to rain. Not very tough.***EDIT 9TH MAY 2020***After leaving it in the sun, day after day on the windowsill to maintain charge, and never using it, unit has just decided the battery is completely empty from being full.
